Why Grow Cannabis In A Greenhouse?
#1 Environmental Control
Growing cannabis in a greenhouse is an ideal choice for areas with harsh and unstable climates. When growing cannabis in greenhouse, growers can control the environment easily.
When grown in a greenhouse, cannabis can also avoid the effects of heavy rainfalls or sunny days, not to mention the harsh climate of the repeated zone.
Although setting up a greenhouse can be more difficult than growing cannabis outdoors or indoors. However, growers do not have to invest as much in equipment to care for cannabis as they do in the indoor. Growers can still take advantage of outdoor lighting and temperatures when needed.
#2 Avoid insects and mold
Another advantage of growing cannabis in greenhouses is that cannabis will avoid the attack of insects and mold.
An enclosed space like a greenhouse will be a wall to prevent insects from entering from outside. So growers don’t need to worry too much about pest problems caused by insects.
And with such an enclosed space, growers can provide the preferred temperature and humidity for their plants. So it can both fight against mold while helping plants grow vigorously.
What To Consider Before Growers Begin Growing Cannabis?
For beginner growers, you need to fill your gaps of experience with serious research. Growing cannabis is quite similar to other crops, but it also requires you to have the proper care.
#1 Cannabis seeds
Before jumping in growing cannabis, beginners need to thoroughly understand the type of cannabis seeds that they are able to take care of as well as suit their needs.
For beginner growers, we recommend that you choose the Autoflower strains. They are a combination of Sativa/ Indica strain and ruderalis, resulting in a strain that automatically flowers without much light exposure.
Beginner growers also need to be careful about selecting cannabis seeds from reputable sources. The quality seed will give you a head start.
#2 Environmental control
As we mentioned above, you must have somehow understood the importance of this factor. When beginner growers set up greenhouses, setting up an environmental control system for cannabis plants is also needed.
Cannabis grows best in preferred temperatures and humidity. To achieve the highest yield and obtain the best quality buds, growers really need to set up devices that can control the temperature, humidity and air in the greenhouse.
#3 Nutrient source
Cannabis is heavy feeders, so growers need to provide the nutrients they need to grow fully. These could be organic matter or fertilizers or additional chemicals that are suitable for a cannabis strain.
Especially at the end of the growing cycle, growers should flush them by feeding water with a pH of 5.8 to 6.2. Many beginner growers are unaware of this practice and cause cannabis to contain residual salts.
#4 Pest and disease control
Growing cannabis in greenhouse means growers must take care of many plants at the same time. It is also an ideal opportunity for pests to grow rapidly from plant to plant.
So, beginner growers really need to be serious about preventing disease and insects in the greenhouse. Growers need to make specific plans for their pest and disease control project.
Shielding vents, preparing beneficial insects or fog systems are essential to prevent unexpected outbreaks.
Growers should also pay attention to pruning so that the growth of dense branches does not cause any mold.
